Description
Technical field
The utility model relates to the quick cooling die of a kind of gravitational casting aluminium recovery.
Background technology
At present, most of Casting Aluminum Piston enterprise all realizes casting mechanizing production.In mechanization production, following gravitational casting technology mature and reliable the most of loosing core, is also most widely used in actual production again.But wherein also there is great problem.Under loose core and cause most piston blank feeding head to be arranged in above the thick enlarged head of piston, thus cause the slower top land of original cooling velocity to be more difficult to cooling, make it to obtain fine and close tissue, mechanical performance is poor.And the key positions such as combustion chamber, interior oil cooling passage, abrasion-proof inserted ring are all positioned at piston crown.Therefore, the inefficacy of most of piston all occurs in this region.Meanwhile, because the cooling of this position is comparatively slow, the bottleneck improving casting production efficiency is become.
Utility model content
The purpose of this utility model is the deficiency existed for prior art, provides a kind of gravitational casting aluminium recovery quick cooling die, improves piston machine performance and casting production efficiency.
The purpose of this utility model is achieved through the following technical solutions.
The quick cooling die of a kind of gravitational casting aluminium recovery, to comprise on the external mold combined up and down block under block and external mold, block is provided with cooling duct with described external mold; On external mold, the backform be mated is arranged at block top, described backform is also provided with cooling duct, horizontal mount pin core on block under external mold, described pin in-core is provided with cooling duct, between the pin core of two, left and right, have close-fitting inner core with it, core inner is provided with cooling duct in described; Except backform cooling duct, in described cooling duct, be equipped with cooling tube.
Described inner core combines by upper and lower two pieces, and described inner core is provided with insulation voids between block under block and inner core.
Under described inner core, block is provided with cooling duct, in described cooling duct, arranges cooling tube.
Described backform combines by upper and lower two pieces, is wherein furnished with cooling duct in block under backform, and on backform, blocks design has casting combustion chamber.
Under described external mold, block and inner core are provided with seam circle between block, achieve external mold, the accurate location of inner core and cooperation dexterously.
The beneficial effects of the utility model have following some:
Adopt the quick cooling die of gravitational casting aluminium recovery of said structure, by by die assembly design mix moulds such as external mold, inner core, backforms, and insulation voids is set between inner core two parts, to greatest extent the cooling fluid of these three die assemblies can be concentrated and act on the thick large part of aluminum piston blank, and reduce the cooling effect of cooling fluid to blank thin-walled portion.Be combined with the PLC control system of existing casting machine, easily can realize the accurate control of cooling water, realize the consecutive solidification of piston blank, ensure that each position of whole piston can obtain better both macro and micro tissue.By design casting combustion chamber in block on backform, effectively can reduce this position blank thickness, accelerate solidifying of this position blank further.Compared with prior art, effectively can improve microscopic structure grade, and then improve the mechanical performance of piston, extend the service life of piston.
Adopt the quick cooling die of gravitational casting aluminium recovery of said structure, effectively can shorten the setting time of aluminum piston blank, improve its casting production efficiency.
Adopt the quick cooling die of gravitational casting aluminium recovery of said structure, can modularized production be realized, shorten the time of mould, improve piston manufacturing enterprise for the adaptibility to response of producing change.Make simultaneously the production of mould, safeguard be more prone to, reduce production cost.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As depicted in figs. 1 and 2, the quick cooling die of gravitational casting aluminium recovery, it is primarily of assembly compositions such as external mold, inner core, backform, seam circle 14 and pin cores 8; External mold is combined by block under external mold 1 and block 2 on external mold, and external mold is furnished with external mold cooling duct 3 in block 2; On external mold, the backform be mated is arranged at block 2 top, backform is also provided with backform cooling duct 5, horizontal mount pin core 8 on block under external mold, pin core cooling duct 9 is provided with in described pin core 8, between the pin core 8 of two, left and right, there is inner core close-fitting with it, be provided with cooling duct at interior core inner; Except backform cooling duct 5, in all cooling ducts, be equipped with cooling tube.
Inner core is combined by block 12 under block on inner core 10 and inner core.Inner core is furnished with insulation voids 11 between block 12 under block 10 and inner core, is furnished with inner core cooling duct 15 in block 11 under inner core, in inner core cooling duct 15, has inner core cooling tube 13, make that the cooling fluid of cooling duct is more concentrated acts on block 12 top under inner core.Insulation voids is also for expanding with heat and contract with cold of block 12 under inner core has reserved space.Under external mold, block 1 and inner core are provided with seam circle 14 between block 10.
Backform is combined by block 6 on block under backform 4 and backform.Backform cooling duct 5 is furnished with in block 4, design part casting combustion chamber 7 in block 6 on backform under backform.
